Should We Use Nutrasweet And Other Artificial Sweeteners
2,046 wordsShould We Use NutraSweet & Other Artificial Sweeteners? Over the years there has been a huge "food fight" concerning the safety of NutraSweet and other artificial sweeteners. In the eyes of the consumer the safety of such products is questionable. In my opinion it isn't safe to use products like this. Though many scientists and other health professionals claim it to be safe I still don't trust these products. In 1981 the little blue packets of NutraSweet appeared on our restaurant tables, and by...

Natural Gas Diesel Fuel
733 wordsWe have known for a long time that eventually our oil deposits will dry up, and it would be helpful at that time if we had some kind of alternative fuel to power all of the machines that we use. Over the past two decades more oil has been pumped than has been found in the world. For this reason scientists have been looking to potential alternative fuels for the future. One of these alternative fuels may come in the form of natural gas. Natural gas has been found to be more plentiful than oil, an...

Daimler Benz Fuel Cell
2,486 words... ironically enough, oil refining. But hydrogen, like gasoline, must be manufactured: it bonds so easily with other elements that it doesn't exist naturally on Earth in pure form. The trouble is that while gasoline is sold in 200, 000 filling stations across the US, the hydrogen infrastructure is minuscule. The result is a chicken-and-egg dilemma: What manufacturers will market hydrogen-powered cars if hydrogen isn't available to drivers? What hydrogen producers will build more plants if hydro...

Ground Level Ozone Environmental Protection Agency
1,441 wordsAir pollution is a very big problem in the United States. A large part of air pollution comes from cars. The Environmental Protection Agency says, "The most polluting activity an average person does everyday is drive their car" (1 fact sheet OMS- 5). Most people probably aren't aware that they are polluting the environment. Maybe if everyone knew how serious this pollution problem is, they would find ways to reduce the pollution. Most pollution that is released by cars comes from the exhaust, ma...

Carbon Atoms Measuring Cylinder
3,479 wordsComparing Energy Release from the Combustion of Alcohols I am going to investigate the energy released by burning alcohol called the enthalpy of combustion. I will be trying to find out how the number of Carbon atoms the alcohol contains effects the enthalpy change that occurs during combustion. The Alcohols are a series of related organic molecules where each member has the -OH (hydroxyl) group in the molecule. The general formula of an alcohol is: Cn H 2 n+ 1 OH, where n is the number of Carbo...

Amount Of Energy Oxygen Atoms
1,983 wordsPlanning In this investigation I will be burning alcohols to heat up a beaker of water. I will be burning five alcohols, methanol, ethanol, propanol, butanol and pentanol. The aim is to find out how much energy is produced when burning these alcohols. An alcohol is a series of organic homologous compounds, with the general formula Cn H n + 1 OH´ . Alcohols react with oxygen in the air to form water and carbon dioxide. The reaction that is involved in burning alcohols is exothermic because ...

Fuel Cells Carbon Dioxide
2,400 wordsThe purpose Fuel Cells Abstract: The purpose of this paper is to inform you why fuel cells are a good source of energy. In principle a fuel cell operates like a battery. Unlike batteries fuel cells dont run down or require recharging. In the first section the energy source will be defined and described. The three sub-sections are; how they work, current us, and the future of fuel cells. In the second section the two criteria chosen will be defined. The two criteria are environmental friendliness...
